What are possible mental risks that can come out of use of DMT?My friend seems to be interested in trying DMT. I did research and of course,...

There is a common misunderstanding about DMT.  Since it is
classified as a Hallucinogen, people tend to think of it working a lot like Ecstasy.
Although they both work on the neurotransmitter Serotonin, which is know to produce the
'euphoria' feeling, DMT works on different Serotonin receptors in the
brain.

The effects of this hallucinogen, is not one of
euphoria... it's the opposite.  The drug opens the other part of your brain... the
fearful hallucinations.  When taking DMT, one has to be mentally prepared for the level
of fear one can exhibit.   The fear can be so frightful, almost like the worst nightmare
of one's life.  Studies have shown that there is an increase risk of Suicide when taking
DMT because that person cannot distinguish the fearful hallucination from
reality.

In addition, if the person taking DMT has any
family history of mental disorders and they posses the genetic trait, this drug has been
known to trigger that trait.

For example, if my brother's
genetic line has a history of Schizophrenia, yet he never shows or demonstrates any
symptoms, taking DMT can open that door.  My brother did indeed try Ecstasy.  4 weeks
later he started hearing voices.  2 years later, he is a full
Schizophrenic.

Is this saying that your friend will become
a Schizophrenic, not necessarily. But taking DMT to illicit this type of hallucination
can indeed trigger a closed door in one's brain.  Hope that makes
sense.
